[Qemu-block] [PATCH v3 3/5] iotests: allow resume_drive by node name

[Andrey Shinkevich]

From: Vladimir Sementsov-Ogievskiy <address@hidden>

After node graph changes, we may not be able to resume_drive by device
name (backing files are not recursively searched). So, lets allow to
resume by node-name. Set constant name for breakpoints, to avoid
introducing extra parameters.
